I have a 2001 XR650R. I ride 100% off-road...mostly woods and MX tracks. The trails that I ride have some rocks and boulders of various sizes. I live in Northern California. I'm still running the stock front tire, and it feels like it just wants to wash out of corners. I have replaced the rear once with a Dunlop ummmm, can't remember the exact tire...anyway, the 650 just ripped it to shreds within 3 or 4 rides. Anyway, there seems to be a lot of good info here, but most of it seems geared more for dual purpose riding. What about strictly off-road? Suggestions much appreciated. Thanks!
